Lack of transmission capacity hampers the integration of the European electricity market, and thereby precludes reaping the full benefits of competition. In this work, we investigate the extent to which transmission grid expansion promotes competition, efficiency and welfare. To this end, we...

Die Umsetzung der Energiewende erfordert einen weiteren starken Ausbau der erneuerbaren Energien in Deutschland. Jedoch werden in der energiepolitischen Debatte immer wieder Zweifel geäußert, ob eine weitgehend auf fluktuierender Wind- und Solarenergie basierende Energieversorgung möglich...

Im Kontext der Energiewende stellt sich die Frage, ob elektrische Speicherheizungen einen Beitrag zur verstärkten Nutzung der fluktuierenden Wind- und Solarenergie und zur Emissionsminderung im Raumwärmebereich leisten können. Im Rahmen eines europäischen Forschungsprojekts wurde am DIW...

We employ a detailed two-stage model to simulate the operation of the Central Eastern European electricity market and network. Implementing different cases of coordination in congestion management between national transmission system operators, numerical results show the beneficial impact of...

Using electricity for heating can contribute to decarbonization and provide flexibility to integrate variable renewable energy. We analyze the case of electric storage heaters in German 2030 scenarios with an open-source electricity sector model. We find that flexible electric heaters generally...

We fit CES and VES production functions to data from a numerical bottom-up optimization model of electricity supply with clean and dirty inputs. This approach allows for studying high shares of clean energy not observable today and for isolating mechanisms that impact the elasticity of...

Green hydrogen can help to decarbonize parts of the transportation sector, but its power sector interactions are not well understood so far. It may contribute to integrating variable renewable energy sources if production is sufficiently flexible in time. Using an open-source co-optimization...

Lack of transmission capacity hampers the efficient integration of the European electricity market, and thereby precludes reaping the full benefits of competition. We investigate to what extent the expansion of the transmission grid promotes competition, efficiency, and welfare. This work...

We develop a dispatch and investment model to study the role of power storage and other flexibility options in a greenfield setting with high shares of renewables. The model captures multiple system values of power storage related to arbitrage, dispatchable capacity, and reserves. In a baseline...

The German energy transition makes it necessary to increase flexibility in the electricity system. Different forms of power storage may play a part in this, yet there is competition with other options on the production or demand side. In the short term, the further expansion of electricity...
